derst'o'od. "Braces ektend from the' frame" 4 downwardly to the side bars 5 and bracing supports 83 are-pivoted"at'their upperends to the side bars 27 and at their lower ends are adjustable upon the frame 4: so that the said side bars 27 may be raised or lowered as-may 'beneeded to-accommodatethe 1n-' creasing height of the stored material. I

The several braces are, of course, so shaped, as shown for instance at 3-lzfin' Fig. 3, as to; pass around the runs of the elevator chains 9 andbesecured to, the side bars 5.

or 2? and thereby attain the desired rigidity by the forks or shelves-,upon the chains.

Braces 3.6 are secured. to thesidesof the platform and the side bars 5' so as to further strengthen the structure. y

.As shown in Figs. ,l and4, the platform may be provided with fingers or bars 37 extendinginwardly from its outer edge so as to-support the material until it is engaged by the forks or shelves of the. carrier and at the same tune prov de space through vlnch said forks or shelves may move. At intervals along the eonveyer chains, 1 secure forks or shelves 38, thesaid chains being connectedat intervals bycross rods or pins 39, as will bereadilyunderstood. Theforks o'r shelvesconsist of tines or fingers t0 hav ing their inner portions coiled-tor wrapped loosely'around one cross-rod 89 and thence extendeddownwardly, asshown at ll, to bear against the outer side of the next suc- 1 ceeding cross rod 39, thereby preventingthe downward movement of the fork uuderthe load imposedthereon. V ,A central tine 12 is provided and has its inner end wrapped loosely around the crossbar 89 but is not extended downwardly therefrom and a bar 43 serves to connect the several tines sothat they will form a rigid structure and will effectually. support therod, as will be readily understood, To preventendwise movement of the shelf or fork, stop collars 44 are socuredupon the rod 39 which carries the shelf at opposite sides of the central tine, as shown inFig.6.'

Theopelfation of the'apparatus .willvbe readily understood. The-hayis placed upon the platform 35 and motion imparted to the pulley 21 so that the 1 described train of gearing is set in'motion 'and the conveyer chams actuated. The forks or shelves are thereby carried'upwardly-through the platform and will engage against the under side of the load or bundle placed thereon and consequently carry the load from the platform up to and over the upper end of the apparatus whereit will be discharged onto the stored material. As the quantity of the stored material increases and. the surface of, the same ,rises within th warehouse,;the frame' may be easily swung to' one orfthe otherside so that the point of delivery will beshifted laterally within the barn or ware;

house and the Qmaterial stored evenly hr ug t th sto ag spa It" wil b readily noted that my apparatus isexccedingly; simple; in the construction and arrangement 0f its partsand -may b outer ends of theQframe, 5l and provided with a sprocket 56 at its centeraover which the conveyer chain 57;runs. .Brackets 58 are secured to the opposite sides of the standard orv supporting bar 59 at the lowcr endiof the sanie and form bearings for. the v shaft-55m the opposite, sides of the sprocket To the upperte nd' of the stamlard or supporting bar 59, I secure brackets or braces 30 in which a shaft til. is journaled,

ing, as will be readily understood, while braces 74 extend from the said supporting these tines project from the ends of the bars or arms 77 which are carried by links of the chain 57, as clearly shown in Fig. 5. If desired, guard rails may be extended between the sprockets 63 and 66 to prevent the bundles from twisting and to insure their dumping as the chain passes over the sprocket 66.

Having thus described the invention, what is claimed as new is:

1. In an apparatus for the purpose set forth, the combination of a conveyerframe, a base frame, a shaft mounted in the outer end of the base frame and the lower end of the conveyer frame, a bracket secured within the base frame at the inner end thereof,

a bracket disposed at the rear of the base I frame, gearing supported by the base frame ,and the bracket therein to operate the con- Oopies of this patent may be obtained for veyer on the conveyer frame, shafts journa'led in the base frame and the bracket at the rear of the same and having a universal connection between a the frame and the bracket, the forward one-of said shafts being connected with said train of gearing, a driving pulley on the rear one of said shafts, and neans for actuating said pulley.

2. The combination of a fixed support, a-

vertical pivot thereon, a con veyer frame disposedin spaced relation to the support, a pivot frame secured rigidly to and extending rearwardlyfrom an upper portion of the conveyer frame to engage the pivot and support the conveyer frame for oscillation in a horizontal plane, a base frame secured to and projecting rearwardly from the lower end of the conveyer frame, a conveyer mounted on the conveyer frame, and gearing supported by theba-se frame and the fixed support to impart motion to the conveyer, said gearing including a universal joint between the base frame and the fixed support whereby the bas'eframe may follow the horizontal oscillation of the pivot frame.

In testimony whereof I affix my signature.
